ACETYLEN E-GAS LAM P.

SPECIFICATION forming part of Letters Patent No. 622,015, dated March 28, 1899.

Application filed November 9, 1898. Serial No. 695,931. (No model) To all whom it may concern:

New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Acetylene-Gas Lamps; and I do hereby declare the following, when taken in connection with the accompanyingdrawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a sectional view of the gas-generating chamber and water-supply and waterdistributing devices of a lamp constructed in accordance with my invention; Fig. 2,,a detached view of the spirally-wound guardtube; Fig. 3, a corresponding view of the spirally-wound water-distributing tube; Fig. 4, a similar view of the water-spreading wire.

My invention relates to an improvement in acetylene-gas lamps, the object being to produce a lamp of simple, compact, and effective construction, composed of few parts and made with particular reference to the avoidance of the use of a fibrous wick, which is open to the objection that it is clogged by the dusty residuum left after the calcium carbid has been disintegrated by the water.

WVith these ends in view my invention consists in an acetylene-gas lamp having a wire water-distributing tube arranged to take the place of a wick.

My invention further consists in an acetylene-gas lamp having a wire water-distributing tube and a water-spreading wire passing longitudinally through the same.

My invention further consists in an acetylene-gas lamp having a wire guard-tube inclosing the water-distributing apparatus.

My invention further consists in certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In carrying out my invention I employ instead of a fibrous wick a water-distributing tube A, made of fine spirally-wound wire and suspended in a vertical position by its upper end from an elbow B, mounted upon the horizontally-arranged water-inlet pipe 0, which is mounted in the dome or cap D of the gas-generating chamber, the lower portion of which is formed bya calcium-carbid receiver or cup E. \Vithin the tube A, I locate a fine water-spreading wire F, which spreads the.

water in its passage downward through the tube and compels it to engage with the coils thereof, by which it is frictionally retarded.

The said water-distributing tube is inclosed in a guard-tube G, made of a coil of heavier wire and at its lower end set over and secured to a short hub H, struck up from the center of a shallow calcium-carbid tray H, which is a trifle smaller in diameter than the internal diameter of the cup Ean'd turned upward aroutidits edge. I do not,however,limit myself to securing the guard-tube G in place in the manner shown, as it may be fastened to the tray H in a variety of other ways. If desired, the tray might be dispensed with and the tube attached to the bottom of the cup. To prevent the water-distributing tube A from displacement within the guard-tube E under the severe jars and concussions of use, I by preference locate upon the water-distributing tube two washers I,wl1'ich may be of any approved material. The employment of these washers is not imperative; but I prefer to use them, especially in case my improved lamp is utilized as a bicycle-lamp. It will be understood that the calcium carbid is introduced into the cup E and rests upon the tray 11. After it has been disintegrated the granulated residuum is removed from the cup by the removal of the tray H',which is lifted out of the cup by taking hold of the guard-tube G, which is prevented from stretching by its provision with a longitudinally-arranged binding-strip G, as seen in Fig. 2. The cup E is formed at its upper edge with external threads, which adapt it to be screwed into an internally-threaded flange D, located at the lower edge of the dome or cap D, provision being made for a washer D to make a gastight joint between the cup and cap. The dome is tapering in form and adapted to receive a burner-tip J, which may also be of any'approved construction. The outer end of the'inlet-tube C carries a head 0, furnished with a needle-Valve K,having a thumbpiece L, furnished witha stop-finger L,which engages with a stop L to prevent the valve from being opened too far. The head 0 is furnished with a cock M, having a key M, the cock providing for draining the watertank N, which is connected with the head 0 by means of a supply-pipe N. However, I

do not limit myself to any particular form or arrangement of tank, nor to connecting the tank with the water-distributing tube in any particular manner, nor to the employment of valves of any particular form, as these details may obviously be made in a variety of ways; nor do I limit myself to forming the cap or cup in any particular way.

I have not shown acombustion-chamber or reflector, because they may take any of the usual forms.

In the use of my improved device the Decdie-valve is turned so as to permit a small body of water to enter the water-distributing tube, which conveys it to the bottom of the guard-tube, between the lower coils of which it finds its way into the mass of calcium carbid within the cup. The generation of gas is at once begun, with the production of considerable heat. The water is now cut off, so that it will flow only drop by drop into the water-distributing tube, in which it will be spread by the waterspreading wire, which forces the water into contact with the coils of the tube, whereby it is prevented from dropping by gravity to the bottom of the tube, through which, on the other hand, it works its way slowly, and perhaps so slowly that it is all taken up before any of it reaches the bottom of the tube. As the water works between the coils of the water-distributing tube it is turned into vapor within the guard-tube, which has now been heated by the heat developed by the gas generated by the water freely admitted into the lamp to start it. The vapor so generated works its way between the coils of the guard-tube and into the calcium carbid, which it acts upon, with the production of gas in the well-known way.

I find my improved means for fractionally distributing water very effective, and by dispensing altogether with the use of a fibrous wick I avoid the clogging of the lamp, the wire coils of the guard-tube lying so close together as to prevent any of the powdered residuum from working its way into 'the interior of the guard-tube and into contact with the water-distributing tube. I may also add that I find with my improved apparatus the carbid is more perfectly reduced than when a wick is employed.

Having fully described my invention, what I claim as new, and desire to seen re by Letters Patent, is

1. In an acetylene-gas lamp, the combination with a carbid-receiver, of a wire water- (listributing tube located within the said receiver, and means for supplying'water to the said tube from which it or itsvapor is ,fed outward into the carbid within the receiver.

2. An acetylene-gas lamp having a 'wire water-distributing tube, and a water-spreading wire passing longitudinally through the same.

3. In an acetylene-gas lamp, the combination with a carbid-receiver, of a wire waterdistributing tube located therein, means for supplying water to the said tube from which it or its vapor is fed outward, and a wire guard-tube also located within the carbidreceiver and inclosing the said water-distributing tube.

4:. In an acetylene-gas lamp, the combination with a carbid-recciver, of a wire waterdistributing tube located therein, means for supplying water to the said tube from which it or its vapor is fed outward, a wire guardtube also located within the receiver and inclosing the said wire water-distributing tube, and a water-spreading wire arranged longitudinally within the water-distributing tube.

5. An acetylene'gas lamp having a wire water-distributing tube permanently secured in place by its upper end, and a wire guardtube adapted to inclose the said Water-distributing tube and secured. by its lower end to the removable carbid-receiver of the lamp.

6. In an acetylene-gas lamp, the combination with a wire water-receiving tube,of a wire guard-tube inclosing the water-distributing tube, and means interposed between the two tubes for preventing the displacement of the water-distributing tube.

7. In an acetylene-gas lamp, the combination with the carbid'receiver or cup thereof, of a tray adapted to fit within the said cup, and a wire guard-tube secured by its lower end to the center of the said tray, and adapted to receive and inclose the water-distributin g devices of the lamp.

8. In an acetylene-gas lamp, the combination with an inlet-tube through which water is brought into the lamp, of a wire water-distributing tube permanently connected at its upper end with the said inlet-tube, a removable carbid receiver or cup, a tray located in the bottom of the said cup, and a guard-tube secured by its lower end to the said tray, and adapted to inclose the water-distributin g tube than which it is larger in diameter.

9. In an acetylene-gas lamp, the combination with a carbid-receiver, of a water-distributing tube located therein, a guard-tube also located within the said receiver and iiiclosing the said water-distributing tube, and means for supplying water to the upper end of the water-distributing tube from which it emerges into the space between it and the guard-tube through which it or its vapor passes into the body of the carbid.

10. In an acetylene-gas lamp, the combination with a carbid-receiver, of a spirallywound water-distributing tube located therein, a spirally-Wound guard-tube also located Within the receiver and inclosing the waterdistributing tube than which it is larger so as to form a space between the two tubes, and means for supplying water to the upper end of the water-receiving tube.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
